Problems solved by technology

However, these areas are characterized in particular by the extreme scarcity of natural water resources, which simply do not allow losses through vaporized water
Although an air-cooled condenser can also be used instead of a water-cooled condenser, the disadvantage is that the cooling effect is much less effective and thus significantly reduces the efficiency of the plant

Embodiment Construction

[0017] The drawing shows an exemplary embodiment of a solar thermal plant installation 1 according to the invention. The solar thermal power plant installation firstly comprises a solar collector 2 for power plant operation, which is here designed as a parabolic trough. The solar heat concentrated by the parabolic trough in the central area thus directly heats and vaporizes the medium circulating in the circuit 3 via said parabolic trough, wherein the steam produced is converted into electrical energy in the turbine 4 . The medium is liquefied again in the condenser 5 , wherein the condenser is cooled by a solar-operated cooling device 6 . The liquefied medium is then vaporized again, thus closing circuit 3 . It should be noted here that, obviously, only the schematic diagrams of the most important components are involved here; the principles of thermal power plant equipment are well known and need not be explained in detail here.

Abstract

The invention relates to a thermal power plant, in particular asolar thermal power plant (1), comprising a gas turbine device, in which a mediumcirculating in a circuit (3) and heated by thermal energy is conducted through a turbine (4) in order to produce electric energy, and subsequently into a capacitor (5) cooled by a cooling device (6) in order to liquefy the medium, wherein the cooling device (6) is designed as a solar-operated cooling device (6) having a closed coolant circuit (7).

Description

technical field [0001] The invention relates to a thermal power plant installation, in particular a solar thermal power plant installation, comprising a gas turbine arrangement, wherein a medium circulated in a circuit, heated by thermal energy, is led through the turbine for the generation of electrical energy and then led through a cooling device Cooled condensers for liquefied media. Background technique [0002] It is well known that in power plant installations thermal energy is converted into electrical energy. Generally, a medium is vaporized by heat energy, and then the vaporized medium drives a turbine, thereby generating electricity. The vapor is then liquefied again in a condenser which is cooled by a cooling device and fed back into the evaporator. Furthermore, the condenser is usually cooled, in particular by means of a water cooling system, ie a cooling tower filled with water is provided or water is drawn from a surrounding natural water source.
